1 An excellence in engineeringan excellence in engineeringquality products for mechanical & fluid powerquality products for mechanical & fluid gear pumps are the most popular pumps used in modern hydraulic feature versatility, strength and long life. Their simple construction ensures cost effective purchasing and service. Thanks to these basic concepts, coupled with ever improving product design and features, result in a quality product manufactured to the very highest standards. Due to the many years of research and experience, accurate material selection, rigid production process and rigorous testing on all aspects of the product range, enables Marzocchi gear pumps to operate under extreme working conditions and transmit high hydraulic power.

2 In addition Marzocchi pumps are produced with good mechanical and hydraulic efficiency, low noise level and their compact dimensions give a low weight too power ratio. A gear pump usually consists of a gear pair supported by two aluminium bushes for groups , and 1P, or bushes with plain bearings coated with anti-friction material for groups 1, 2, 3 and 4, a body, a securing flange and a of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal, the outer lip being a dust seal) for groups , and 1P, or two opposed single-lip seal rings (the outer being a dust seal) for groups 1, 2, 3 and body, flange and cover are made of special high-resistant aluminium alloys for minimized deformation even when subject to high pressure, be it continuous or intermittent or peak pressure.

3 The body is profiled by means of extrusion, whereas flange and cover are obtained by means of die-casting (gravity die-casting for some models). Gears are made of special steel. Their manufacturing process includes case-hardening and quench hardening. The gears are ground and fine finished so as to have a high degree of surface finishing. Proper tooth profile design and geometric proportions ensure low pulsation levels and low noise levels during pump operation. Bushes are made of special low-friction and high-resistant aluminium alloy and manufactured from die-casting. Special compensation zones onto flange and cover, insulated by special seals with anti-extrusionrings, allow fully free axial and radial movement to the bushes, which is proportional to pumpoperating pressure.

4 In this way, internal leakage is dramatically reduced, thus ensuring veryhigh pump performance (both in terms of flow and overall) and proper lubricationto the moving pump Pump Basic Design - simple construction, long and useful life. 01737 Basic pump parts1- 2- Driven gear3- Bushings4- Body5- Flange6- Cover7- Rotary shaft seal8- Compensation seals9- Anti-extrusion seals10- CirclipDrive gearGHM Series Gear MotorsALM Series Gear MotorsALPC/GHPC Series Short Multiple PumpsThe GHP series offer identical configurations to the ALP series and guarantees extreme reliability in very highpressure applications. Ideal for mobile applications from agricultural to construction machines as the cast iron allows more flange, cover andport GHM series offer identical configurations to the ALM series but more robust thanks to the cast iron front flange and rear production rates, performance consistency and absolute reliability ensure this a benchmark product for the hydraulic power pack pump for applications which require a fast approach and/or return of the actuator at low loads and slow motion of the actuator at high loads.

5 Log splitters, compactors and and mechanical efficiencies as well as low noise levels are further benefits of this product range includes pumps of different displacements (up to 200cc/rev) in a full aluminium configuration, able to withstand medium to high pressures and using different versions of flanges (European, German and SAE), porting and shafts. Mono-directional as well as reversible solution are medium to high pressure rates the ALM series is ideal for mobile and industrial sectors. Mono-directional andbi-directional with internal and external drain range and very high performance of these pumps integrated in to micro power packs make them ideal for many applications from aerospace to marine, medical to and flexibility are the characteristics of these pumps.
